BROARDSIDE Posted June 23, 2005 Share Posted June 23, 2005 HEY ALL IM JUST GONNA BE FITTING A TURBO KIT TO MY N/A SUPRA I NEED SOMETHING THAT WILL TELL ME MY FUEL RATIO TO BE SURE I AM NOT RUNNING LEAN IVE SEEN THE KNOCK AMP (SEEMS A BIT PRICEY) ANY SUGESTIONS Link to comment Share on other sites More sharing options...
Alex Posted June 23, 2005 Share Posted June 23, 2005 Take a step back mate, can you give us the full spec of the car as it will stand once you've fitted everything you've got already. Knock Amps won't tell you your AFR's you need an AEM or similar AFR gauge with sensor. The sensor has to be mounted in the exhaust. And stop using CAPS!

Homer Posted June 23, 2005 Share Posted June 23, 2005 You'll need to state which ECU you are planning on using. Also I'm pretty sure 440cc injectors are going to be too small for an Na-T conversion. Edited - just spoted the SAFC2 listed! I think you'll need a boost controller too. Link to comment Share on other sites More sharing options...
Alex Posted June 23, 2005 Share Posted June 23, 2005 You'll need to state which ECU you are planning on using. Also I'm pretty sure 440cc injectors are going to be too small for an Na-T conversion. He did, SAFCII, piggybacking the stocker. 440's will be fine as long as he's not going for mega boost. Anything over 400bhp you can forget about. Then returning to the question, I use an AEM 52mm AFR gauge with AEM WB02 sensor plumbed into the exhaust. What pressure is the spring in the wastegate...EBC not needed IMO if the spring is properly rated. Link to comment Share on other sites More sharing options...
Ian C Posted June 23, 2005 Share Posted June 23, 2005 just spoted the SAFC2 listed! Fat lot of use that'll be in an NA conversion. How is it going to know what positive pressure the engine is seeing? -Ian Link to comment Share on other sites More sharing options...
JustGav Posted June 23, 2005 Share Posted June 23, 2005 440CC Injectors x 6 (fits in the stock rail) As others have said, why go to 440cc... pretty sure they are stock injectors ie no need to change them... Mind you I've never actually checked what the NA used.. Gav Link to comment Share on other sites More sharing options...
JustGav Posted June 23, 2005 Share Posted June 23, 2005 SAFC wouldn't be up to job I wouldn't have thought... Emanage with a pressure sensor so you can control the fueling perhaps?? (I could be talking complete bollocks tho as well, since I gave up on the NA-T route) Also I would careful of using the nitrous, since I assume you are using stock box, and stock diff... they might be the weak point of the whole setup Gav Link to comment Share on other sites More sharing options...
Guest Terry S Posted June 23, 2005 Share Posted June 23, 2005 I think the NA's run 380cc injectors, and I also believe they are top feed so the 440's wont fit the rail. Not 100% on all that though Link to comment Share on other sites More sharing options...
Ian C Posted June 23, 2005 Share Posted June 23, 2005 They are 370cc I think, can't recall if there is a difference in the rail layout though. I don't think there is as I've looked at Digsy's NA engine a few times and I can't recall going "blimey - that's different" at the fuel rail. -Ian Link to comment Share on other sites More sharing options...

(I could be talking complete bollocks tho as well, since I gave up on the NA-T route) That'd work, pull the airflow signal right back to compensate for the bigger injectors, then use the addinj map to add duty cycle when on positive boost. Could work rather well -Ian Link to comment Share on other sites More sharing options...
JustGav Posted June 23, 2005 Share Posted June 23, 2005 I do come up with some interesting ideas once in a while... I'm actually considering install an emanage onto a bike when I do a turbo installation on it... either that or on a morris minor I've just bought for a laugh... Morris minor with a single toyota turbo.... could be a laugh... Gav Link to comment Share on other sites More sharing options...
BROARDSIDE Posted June 23, 2005 Author Share Posted June 23, 2005 what the F**K have you lot just said im not as clued up as i should be but im getting there the way i see it is the whole thing comes as a kit so im hoping for initial setup to be ok then i can start playing with boost controllers and shi* like that but if i just get a wide band 02 sensor then i can adjust the fueling with the SAFC2 that i have got installed i cant see any point in buying a e-manage controller as the mapping will only do the same sort of thing as the SAFC 2 (obviousley with more acurate results ) what u think talking sh** or am i on the right lines Link to comment Share on other sites More sharing options...

Converting an NA to a turbo is not a matter of just bolting on bits from an "NA-T parts pack" Rather than let this thread drag on for ages with people explaining every aspect of single turbo conversions, I highly recommend you give Terry S (Vortex) a call tomorrow. Terry or one of the guys there will be able to discuss your requirements in much more detail than is possible on a forum. They've done numerous single conversions and have a kit for an NA too.

CJ Posted June 23, 2005 Share Posted June 23, 2005 Judging from his list of BL products, I assume he has been speaking to Terry / Mig already? Link to comment Share on other sites More sharing options...
Homer Posted June 23, 2005 Share Posted June 23, 2005 Not sure about that CJ, I doubt Terry would recommend a T4 turbo (laaarge) with 75 shot NOS and 440cc injectors! Why bother with NOS if you're going for a low boost big size turbo... It just looks like a total mis-match of parts. Link to comment Share on other sites More sharing options...
CJ Posted June 23, 2005 Share Posted June 23, 2005 Well, if he hasn't been speaking to Terry, that list must just be wishful thinking then because Vortex are the only suppliers of BL kit in the UK. Link to comment Share on other sites More sharing options...
Ian C Posted June 23, 2005 Share Posted June 23, 2005 if i just get a wide band 02 sensor then i can adjust the fueling with the SAFC2 that i have got installed i cant see any point in buying a e-manage controller as the mapping will only do the same sort of thing as the SAFC 2 (obviousley with more acurate results ) what u think talking sh** or am i on the right lines Option a) for me. The sAFC cannot do anything other than change the airflow signal to move where you are on the fuel map. The NA supra ECU has no map for positive pressure and there is no sensor in the system to measure positive pressure so when you go on boost your MAF sensor will go out of range very quickly and christ knows how much duty cycle it will run - maybe 100% as it thinks it's a gorilla 3.3l at 1000ft below sea level for a moment, but that's the end of it's range. Good luck in trying to get any meaningful fuel-to-boost-pressure curve out of that. Harsh words maybe, but couple the inability to map fuelling when on boost (a bit of a disaster when you are adding a turbo) with too-small injectors and too-large a turbo, and you are putting together an expensive boat anchor... My advice is, do a lot of reading and a modicum of planning before any spending. -Ian Link to comment Share on other sites More sharing options...

Homer Posted June 25, 2005 Share Posted June 25, 2005 Hi Broadside, like I said, I really didn't mean to cause offence or anything. Since you seem to be quite new to modifying forced induction cars and clearly have very big plans for your Supra, you're really best of speaking to one of the 'real' experts (After all you don't want to bolt anything on and find your engine going 'pop') Terry S and the rest of the Vortex lads know their stuff so you're really best off speaking to one of them first so they can set some basic ideas about tuning your cars. Have you spoken to them yet mate? Link to comment Share on other sites More sharing options...
JustGav Posted June 25, 2005 Share Posted June 25, 2005 Here is the kit list from someone on supraforums who has done it...

adi2009 Posted June 26, 2005 Share Posted June 26, 2005 A bit of a but are there any differences in the air metering system between the J-spec NA's and the NA's in the USA. Because i have seen people on supraforums.com stating that they run NA-T kits with only an SAFC (but at below 6psi) and much of the components that BROARDSIDE said he was getting. Link to comment Share on other sites More sharing options...
Homer Posted June 26, 2005 Share Posted June 26, 2005 Adi, That might be possible but 6psi is extremely low pressure. I just can't see the point of running such a big laggy turbo like the T4 and then run such low pressure. Decent boost (if you can call it that) wouldn't be reached until very high rpm and even then its over in no time! It still looks like a complete fudge of a turbo system IMO.

BROARDSIDE Posted June 26, 2005 Author Share Posted June 26, 2005 ok ok look perhaps i have not explained myself properly ill start againg :):) my supe at the mo is an n/a i have got the safcII installed just cos i got it cheap (and it looks good) (sad i know) i have got a boostlogic stage 2 kit coming now this kit is complete and all the parts that i mentioned earlier are in it i have been told that i only have put the system on and it wont need no tuning initialy after that i can then get the extras to start tuning i have an the 75 shot of nitrous installed now but i wont be using it untill i have sorted and tuned the turbo and i am happy with the setup i hope this is not to much wishfull thinking but the kit is suposed to be complete and 100% (so i have been told ) Link to comment Share on other sites More sharing options...
